Surface Diffusion in SnTe‐PbTe Monolayer Lateral Heterostructures

open access: yesAdvanced Functional Materials, EarlyView.
The lateral heterostructures between 2D materials often suffer from the interdiffusion at the interfaces. Here, a surface diffusion mechanism is found to be dominating at the interfaces between semiconducting SnTe and PbTe monolayers. Atomically sharp interfaces can be achieved by suppressing this diffusion process. ABSTRACT The construction of complex

Quasi‐Static to Supersonic Energy Absorption of Nanoarchitected Tubulanes and Schwarzites

open access: yesAdvanced Functional Materials, EarlyView.
Nanoarchitected energy‐absorptive Tubulanes exhibit record energy absorption under quasi‐static conditions and exceptional inelastic energy dissipation under 750 m s−1 ballistics impact, with high performance spanning strain rates of 12 orders of magnitude.

A Natural Law of Succession

open access: yes, 1995
Consider the problem of multinomial estimation. You are given an alphabet of k distinct symbols and are told that the i-th symbol occurred exactly n_i times in the past.

Deciphering Small Molecule Diffusion Parameters Across Light Responsive Polymersome Membranes

open access: yesAdvanced Functional Materials, EarlyView.
Light‐responsive polymersomes bearing donor–acceptor Stenhouse adducts (DASAs) enable programmable control over small‐molecule transport across synthetic membranes. By systematically varying DASA density, an optimal functionalization regime is identified that maximizes light‐gated permeability.

Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges

open access: yesAdvanced Functional Materials, EarlyView.
Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.

The moral problem is a Hume problem [PDF]

open access: yesBelgrade Philosophical Annual
The moral problem, as articulated by Smith, arises out of the attempt to introduce the experimental method of reasoning into moral subjects, developed by Hume.

Bio‐Inspired Magnetically Tunable Structural Colors from Elliptical Self‐Assembled Block Copolymer Microparticles

open access: yesAdvanced Functional Materials, EarlyView.
Cephalopod‐inspired photonic microparticles with dynamic structural coloration are fabricated via confined self‐assembly of linear block copolymers into ellipsoids containing stacked lamellae. Embedded superparamagnetic nanoparticles enable rapid magnetic alignment, restoring vivid, angle‐dependent color.

Liberdade, lei natural e direito natural em Hobbes: limiar do direito e da política na modernidade Freedom, natural law and natural right in Hobbes: threshold of law and politics in modernity

open access: yesTrans/Form/Ação, 2009
Liberdade e poder são dois temas que se correlacionam ao longo da história da filosofia política moderna. Nos textos de Hobbes, a ideia da liberdade como ausência de impedimentos às ações ajuda-nos a pensar o dever de obediência ao poder soberano e as ...
